Abstract

PURPOSE: To obtain a grip training device easily attached and detached to and from a club by providing a grip pressure detecting element with a signal means for generating a signal in response to the grip pressure in the periphery of the grip of a golf club. CONSTITUTION: A grip pressure detecting element 2 fixed to the lower side of a grip 3 of a golf club 4 is formed by a multi-level strip switch 5 stored in a housing 6, and pressed to the lower side of the grip of the club and fixed by a string. A signal device 9 is fixed near the detecting element between the club head and the pressure detecting element, and then electrically put in the connecting state by a rapid electric coupling device. In the condition where the power is not applied, a block 18 keeps three elastic contact bands 15-17 in the separated insulating relationship, and when pressure is applied to the outer switch contact band 15, electric contact is caused between the contact bands 15-17 according to the applied pressure to let a buzzer 30 go. Thus, it is possible to obtain a grip training device easily attached and detached to and from the club.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a training aid that can be easily attached to and removed from the grip of any golf club to assist golfers in developing optimal grip pressure. Regarding ingredients.

BACKGROUND OF THE INVENTION In a golf swing, it is important to hold the grip (handle) with the same fairly light grip pressure from beginning to end. When the grip pressure is appropriate, you will feel like you have control over the club.

You should feel the weight of the club head. Grip pressure must remain constant throughout set-up, backswing, and follow-through.

Gripping the club too tightly can stiffen your forearms and cause a slow swing. Conversely, if the grip is too loose, other problems arise, such as overswinging or hitting the ground before hitting the ball.

Experienced golfers recognize that a good grip is an essential part of the strategy for improving the golf game.

Numerous training aids have been invented to measure a golfer's grip pressure, including the Davi
d R.A. Budney, U.S. Pat. No. 4,138,118, issued February 6, 1979; Walter
No. 4,103,896 issued August 1, 1978 to R. Lorang and RoW, 5 earle.
U.S. Patent No. 3°323.3 issued June 6, 1967
There is something like No. 67. The Budney invention shows a golf grip that uses strain gauges fixed at selected locations on the grip. This strain gauge is connected to a remote recorder that outputs a series of graphs that can be compared to those of a professional golfer. The Orang invention shows a grip training device that includes a switch lever on one side of the grip of a golf club.

When extra force is applied to the middle finger of the supporting hand, a lever closes the circuit and a signal means attached to the club emits a signal. In the 5earle invention, a plurality of grip pressure sensing sensors are provided on the grip of a golf club to respond to the grip pressure of both hands.

This sensor is part of a bridge circuit that causes a meter mounted on the club to display grip pressure values.

While the above-mentioned patents disclose pressure-responsive grips, the mounting flexibility, wide applicability, and flexibility found in the present invention! There is no disclosure of a grip training device that is sectionable.

SUMMARY OF THE INVENTION The general purpose of the present invention is to improve upon conventional golf grip training devices by increasing the flexibility and range of use.

A particular object of the present invention is to provide a grip training device that a golfer can easily attach and detach from his or her club.1 Although the device of the present invention can be attached to a golf club, it is is designed as a removable accessory at the golfer's choice.
The device of the present invention can be used by both right-handed and left-handed golfers since the golfer can attach it to his or her club.

Another object of the invention is to provide a grip pressure indicator that is responsive to at least two specific grip pressures.

The change in grip pressure response is caused by an electrical switch in a series circuit comprising a battery, a pressure sensor, and an audible signal device. By varying the grip pressure range, it can be used by golfers with different levels of strength, skill, and experience.

Yet another object of the present invention is to provide a device that self-analyzes the force of gripping a club using sound. Audible signaling devices attached to the golf club are preferred over visual signals in that they allow the golfer to concentrate on the ball without distraction while grip pressure is being detected.
